K&N 69 Series Typhoon Intake Systems Reviews

For one reason or another I heard nothing but bad remarks about this kit. The instructions were very straightforward in informative. I cut out the lower front valance "vent" so that the filter had complete access to fresh air. This is THE most effective power per dollar investment for the S2000. I KNOW I gained at least 9-12bhp (more than the claimed advertisement) from the kit's placement and by cutting away the front bumper "vent". Not to mention I'm now AVERAGING 26-27mpg! The cutting of the front bumper "vent" made a significant difference in power at speed and the angry growling sound from 6k-9K RPM.
